Chickenpox is treated at home with a combination of itch relief, fever management, and time. Most cases clear up within 7 to 10 days without prescription medication. The goal is to keep yourself or your child comfortable, prevent scratching that leads to scars, and watch for the few complications that need medical attention.
Relieving the Itch
The itch is usually the worst part of chickenpox, and managing it well does more than improve comfort. It also prevents scratching, which is the main cause of permanent scarring. Several approaches work best when combined.
Lukewarm or cool baths are one of the most effective options. Add a handful of oatmeal ground to a powder (or a commercial oatmeal bath product) to the water and soak for 15 to 20 minutes. Avoid hot water, which makes itching worse. After the bath, pat skin dry gently rather than rubbing.
Calamine lotion can be dabbed directly onto blisters to help dry them out and soothe the skin. It contains a mix of phenol, menthol, and camphor that creates a mild cooling sensation. Apply it as needed throughout the day, but avoid getting it near the eyes. For children, keeping fingernails trimmed short and putting cotton mittens or socks on their hands at night can prevent unconscious scratching while they sleep.
Managing Fever and Pain
Acetaminophen (Tylenol) is the safest choice for reducing fever and discomfort during chickenpox. Ibuprofen (Advil, Motrin) is also an option for children and adults, though some doctors prefer acetaminophen as the first choice.
Never give aspirin to a child or teenager with chickenpox. Aspirin use during chickenpox or flu has been linked to Reye’s syndrome, a rare but serious condition that causes swelling in the liver and brain. This applies to any product containing aspirin, including some combination cold medicines, so check labels carefully.
Eating and Drinking With Mouth Blisters
Chickenpox blisters sometimes develop inside the mouth and throat, making eating painful. Cold, soft, bland foods are easiest to tolerate: think smoothies, applesauce, yogurt, and frozen yogurt pops. Avoid anything acidic or salty, like orange juice, tomato sauce, or pretzels, which will sting open sores.
Staying hydrated matters more than eating full meals during the worst days. Offer water, diluted juice, or ice chips frequently, especially for young children who may resist drinking when their mouth hurts.
When Antiviral Medication Helps
Most healthy children under 12 don’t need antiviral medication. Their immune systems handle the virus on their own. But for certain groups, prescription antivirals can shorten the illness and reduce severity, as long as treatment starts within 24 hours of the rash appearing. That window is important: after the first day, the benefit drops significantly.
The American Academy of Pediatrics recommends considering antiviral treatment for:
- Healthy people older than 12 (teens and adults tend to get sicker)
- People with chronic skin or lung conditions
- People taking corticosteroids, even short courses
- Pregnant women who develop complications like pneumonia
- Anyone with a weakened immune system
If you fall into one of these groups and notice the first spots appearing, contact your doctor that same day. Waiting even an extra 12 hours can make the medication less effective.
How Long You’re Contagious
A person with chickenpox becomes contagious 1 to 2 days before the rash even appears, which is why it spreads so easily. You remain contagious until every single blister has crusted over. For most people, that takes about 5 to 7 days after the rash starts.
During this time, stay home from work or school. The virus spreads through the air (not just through touching blisters), so being in the same room as others is enough to transmit it. If someone in your household has been exposed but hasn’t had chickenpox or the vaccine, getting vaccinated within 3 to 5 days of exposure may prevent the illness entirely or make it significantly milder.
Preventing Scars
The blisters themselves don’t usually leave scars. Scratching does. Every time a blister is torn open, it creates a deeper wound that’s more likely to scar and more vulnerable to bacterial infection.
Wear soft, loose clothing that won’t rub against blisters. During the active blister phase, minimize soap use on affected areas and instead cleanse gently with warm water. Scrubbing with soap can irritate open lesions and slow healing. Once the crusts have naturally fallen off on their own, you can return to normal bathing. At that point, if any marks remain, a doctor can recommend topical scar treatment creams to improve their appearance over time.
Signs of Complications
Chickenpox is usually mild, especially in vaccinated children who catch a breakthrough case. But bacterial skin infections are the most common complication, and they happen when scratched blisters let bacteria in. Watch for skin around a blister that becomes increasingly red, warm, swollen, or painful, or for blisters that start oozing thick or discolored fluid rather than clear liquid. These signs suggest a secondary infection that may need antibiotics.
More serious complications are uncommon but worth knowing about. A fever that spikes again after several days of improvement, difficulty breathing, persistent vomiting, severe headache with neck stiffness, or confusion and difficulty walking are all reasons to seek immediate medical care. These can signal pneumonia or inflammation of the brain, both of which require hospital treatment. Adults, newborns, pregnant women, and immunocompromised individuals face the highest risk for these severe outcomes.
